Nova Compute Driver
Blueprint: https://blueprints.launchpad.net/octavia/+spec/nova-compute-driver
Octavia needs to interact with nova for creation of VMs for this version. This spec will flesh out all the methods described in the compute-driver-interface with nova VM specific commands.
Problem description
This spec details operations for creating, updating, and modifying amphora that will hold the actual load balancer. It will utilize the nova client python api version 3 for the nova specific requests and commands.
Proposed change
Expose nova operations
- Build: Will need to build a virtual machine according to
configuration parameters
- Will leverage the nova client ServerManager method "create" to build a server
- Get: Will need to retrieve details of the virtual machine from nova
- Will leverage the nova client ServerManager method "get" to retrieve a server, and return an amphora object
- Delete: Will need to remove a virtual machine
- Will leverage the nova client ServerManager method "delete" for removal of server
- Status: Will need to retrieve the status of the virtual machine
- Will leverage the aforementioned get call to retrieve status of the server
